A community is like a ship; everyone ought to be
prepared to take the helm.

—Henrik Ibsen

Distributed Universal Number Discovery, or DUNDi, is a service
discovery protocol that can be used for locating resources at remote
locations. The original intention of DUNDi was to permit decentralized
routing among many peers using a General Peering Agreement (GPA). The GPA
(available at http://dundi.com/PEERING.pdf) is
intended to take on the role of a centralized control authority with a
document to create a trust relationship among the peers in the cloud. While
the idea is interesting and sound, the GPA has not taken off. That doesn’t
mean the DUNDi protocol itself hasn’t found a home though: the original
intention of DUNDi has been expanded so that now it doesn’t just act as a
location service, but can be used to request and pass information among
peers.
